Can You Carry a Small Swiss Army Knife in Japan?

A small Swiss Army knife seems harmless. It fits on a keychain, and its blade may be shorter than your little finger. In many places, people carry one simply because it might come in handy.

 

In Japan, that can cause a problem. A blade measuring 6 centimeters or less is outside the main blade-length restriction in Japan’s firearms and swords law, but that does not mean it is automatically legal to carry everywhere. Under the Minor Offenses Act, carrying a knife concealed without a legitimate reason may still be an offense. The Tokyo Metropolitan Police specifically warns that even a small multitool or Swiss Army knife carried like an accessory can be subject to enforcement.

 

The reason matters. Taking a knife to a campsite where you intend to use it is different from leaving one on your keychain every day “just in case.” And calling it a tool does not settle the question: a tool with a blade can also be treated as a weapon when carried without a legitimate purpose.

 

If you are visiting Japan, check your pockets, bag, and keychain before going out. That tiny Swiss Army knife you barely think about at home may attract serious attention there.
